TECHNICAL FIELD

Described herein are ureas which are useful for treating pain, cough, bladder overactivity, urinary incontinence, or conditions and disorders modulated by the TRPV1 channel. Pharmaceutical compositions comprising said compounds and methods for treating pain, diabetic neuropathy, cough, asthma, bladder overactivity, urinary incontinence, anxiety, or conditions and disorders modulated by the TRPV1 channel are also included.

BACKGROUND

Nociceptors are primary sensory afferent (C and Aδ fibers) neurons that are activated by a wide variety of noxious stimuli including chemical, mechanical, thermal, and proton (pH<6) modalities. The lipophillic vanilloid, capsaicin, activates primary sensory fibers via a specific cell surface capsaicin receptor, cloned as the transient receptor potential vanilloid-1 (TRPV1). TRPV1 is also known as vanilloid receptor-1 (VR1). The intradermal administration of capsaicin is characterized by an initial burning or hot sensation followed by a prolonged period of analgesia. The analgesic component of the TRPV1 receptor activation is thought to be mediated by a capsaicin-induced desensitization of the primary sensory afferent terminal. Thus, the long lasting anti-nociceptive effect of capsaicin has prompted the clinical use of capsaicin analogs as analgesic agents. Further, capsazepine, a capsaicin receptor antagonist, can reduce inflammation-induced hyperalgesia in animal models. TRPV1 receptors are also localized on sensory afferents, which innervate the bladder. Capsaicin or resiniferatoxin have been shown to ameliorate incontinence symptoms upon injection into the bladder.

The TRPV1 receptor has been called a “polymodal detector” of noxious stimuli since it can be activated in several ways. The receptor channel is activated by capsaicin and other vanilloids, and thus is classified as a ligand-gated ion channel. The TRPV1 receptor activation by capsaicin can be blocked by the competitive TRPV1 receptor antagonist, capsazepine. The channel can also be activated by protons. Under mildly acidic conditions (pH 6-7), the affinity of capsaicin for the receptor is increased, whereas at pH<6, direct activation of the channel occurs. In addition, when membrane temperature reaches 43° C., the channel is opened. Thus heat can directly gate the channel in the absence of ligand. The capsaicin analog, capsazepine, which is a competitive antagonist of capsaicin, blocks activation of the channel in response to capsaicin, acid, or heat.

The channel is a nonspecific cation conductor. Both extracellular sodium and calcium enter through the channel pore, resulting in cell membrane depolarization. This depolarization increases neuronal excitability, leading to action potential firing and transmission of a noxious nerve impulse to the spinal cord. In addition, depolarization of the peripheral terminal can lead to release of inflammatory peptides such as, but not limited to, substance P and CGRP, leading to enhanced peripheral sensitization of tissue.

Recently, two groups have reported the generation of a “knock-out” mouse lacking the TRPV1 receptor. Electrophysiological studies of sensory neurons (dorsal root ganglia) from these animals revealed a marked absence of responses evoked by noxious stimuli including capsaicin, heat, and reduced pH. These animals did not display any overt signs of behavioral impairment and showed no differences in responses to acute non-noxious thermal and mechanical stimulation relative to wild-type mice. The TRPV1 (−/−) mice also did not show reduced sensitivity to nerve injury-induced mechanical or thermal nociception. However, the TRPV1 knock-out mice were insensitive to the noxious effects of intradermal capsaicin, exposure to intense heat (50-55° C.), and failed to develop thermal hyperalgesia following the intradermal administration of carrageenan.

In the course of characterizing analgesic properties of structurally distinct TRPV1 antagonists, multiple investigators have observed core body temperature elevating (“hyperthermic”) attributes of these compounds in rodent behavioral models of pain (Swanson, D. M. et al., J. Med. Chem., 2005, 48, 1857; Gavva, N. R. et al., J. Pharmacol. Exp. Ther., 2007, 323, 128; Steiner, A. A. et al., J. Neurosci., 2007, 27, 7459; Tamayo, N. et al., J. Med. Chem., 2008, 51, 2744; Gavva, N. R. et al., J. Neurosci., 2007, 27, 3366). Often modest (0.5° C.), the associated temperature elevation can be considerably more robust (1-2° C.), and also has been reported preclinically in dogs and monkeys (Gavva, N. R. et al., J. Pharmacol. Exp. Ther., 2007, 323, 128; Gavva, N. R. et al., J. Neurosci., 2007, 27, 3366) and in human subjects in the course of clinical trials (Gavva, N. R. et al., Pain, 2008, 136, 202). These effects have the potential to be self-limiting; they are generally transient and attenuate with repeat dosing (Gavva, N. R. et al., J. Pharmacol. Exp. Ther., 2007, 323, 128). The temperature effects are considered to be mechanism based (Iida, T. et al., Neurosci. Lett., 2005, 378, 28) since TRPV1 null mice show no deficits in thermoregulation, even when dosed with antagonists that elevate temperature in wild-type mice (Steiner, A. A. et al., J. Neurosci., 2007, 27, 7459; Garami, A. et al., J. Neurosci., 2010, 30, 1435).

Efforts to understand and separate the nociceptive and thermoregulatory functions of TRPV1 have led to directed research to identify antagonists that afford analgesic benefit without affecting core body temperature (Lehto, S. G. et al., J. Pharmacol. Exp. Ther., 2008, 326, 218) or imparting insensitivity to noxious heat, as observed in TRPV1 null mice (Caterina, M. J. et al., Science, 2000, 288, 306).

Certain chromane and indane derivatives that are TRPV1 modulators are reported in the following publications: WO 2005/040100, WO 2007/042906, WO 2008/059339, US 2006/0128689, WO 2007/121299, US 2008/0153871, WO 2008/110863, WO 2008/091021, WO 2007/010383, WO 2010/010935, WO 2010/045401, WO 2010/045402, U.S. Pat.

We describe herein certain TRPV1 antagonists that have little or no significant effect on the sensation of noxious heat.

Compounds described herein can exist as stereoisomers wherein asymmetric or chiral centers are present. These stereoisomers are “R” or “S” depending on the configuration of substituents around the chiral carbon atom. The terms “R” and “S” used herein are configurations as defined in IUPAC 1974 Recommendations for Section E, Fundamental Stereochemistry, Pure Appl. Chem., 1976, 45: 13-30.

It can be appreciated two or more asymmetric centers can be present in the present compounds, hence several diastereomers and enantiomers of the exemplified structures can often be possible, and that pure diastereomers and enantiomers represent preferred embodiments. It is intended that pure diasteromers, pure enantiomers, and mixtures thereof, are within the scope of the invention.

Various stereoisomers (including enantiomers and diastereomers) and mixtures thereof (including racemates) are contemplated. Individual stereoisomers of present compounds can be prepared synthetically from commercially available starting materials that contain asymmetric or chiral centers or by preparation of racemic mixtures followed by resolution of the individual stereoisomer using methods that are known to those of ordinary skill in the art. Examples of resolution are, for example, (i) attachment of a mixture of enantiomers to a chiral auxiliary, separation of the resulting mixture of diastereomers by recrystallization or chromatography, followed by liberation of the optically pure product; or (ii) separation of the mixture of enantiomers or diastereomers on chiral chromatographic columns.

For example, compounds of formula (I-f) wherein L is a bond can be isolated as any one of the stereoisomers as shown below, or mixtures of two or more of stereoisomers of various ratios:

It is to be understood that the substituents and variables, and combinations thereof, in formula (I-f-i) and (I-f-ii) have the same values as those discussed for (I-f) above.

Geometric isomers can exist in the present compounds. Thus various geometric isomers and mixtures thereof resulting from the disposition of substituents around a carbon-carbon double bond, a carbon-nitrogen double bond, a cycloalkyl group, or a heterocycle group are part of the invention. Substituents around a carbon-carbon double bond or a carbon-nitrogen bond are designated as being of Z or E configuration and substituents around a cycloalkyl or a heterocycle are designated as being of cis or trans configuration.

Within the present application it is to be understood that compounds disclosed herein can exhibit the phenomenon of tautomerism.

Thus, the formula drawings within this specification can represent only one of the possible tautomeric or stereoisomeric forms. It is to be understood that the invention encompasses any tautomeric or stereoisomeric form, and mixtures thereof, and is not to be limited merely to any one tautomeric or stereoisomeric form utilized within the naming of the compounds or formula drawings.

Compounds of the invention can exist in isotope-labeled or isotope-enriched form containing one or more atoms having an atomic mass or mass number different from the atomic mass or mass number most abundantly found in nature. Isotopes can be radioactive or non-radioactive isotopes. Isotopes of atoms such as hydrogen, carbon, phosphorous, sulfur, fluorine, chlorine, and iodine include, but are not limited to, ²H, ³H, ¹³C, ¹⁴C, ¹⁵N, ¹⁸O, ³²P, ³⁵S, ¹⁸F, ³⁶Cl, and ¹²⁵I. Compounds that contain other isotopes of these and/or other atoms are within the scope of this invention.

In another embodiment, the isotope-labeled compounds contain deuterium (²H), tritium (³H) or ¹⁴C isotopes. Isotope-labeled compounds of this invention can be prepared by the general methods well known to persons having ordinary skill in the art. Such isotope-labeled compounds can be conveniently prepared by carrying out the procedures disclosed in the Examples and Schemes sections by substituting a readily available isotope-labeled reagent for a non-labeled reagent. In some instances, compounds can be treated with isotope-labeled reagents to exchange a normal atom with its isotope, for example, hydrogen for deuterium can be exchanged by the action of a deuteric acid such as D₂SO₄/D₂O. In addition to the above, relevant procedures and intermediates are disclosed, for instance, in Lizondo, J et al., Drugs Fut, 21(11), 1116 (1996); Brickner, S J et al., J Med Chem, 39(3), 673 (1996); Mallesham, B et al., Org Lett, 5(7), 963 (2003); PCT publications WO1997010223, WO2005099353, WO1995007271, WO2006008754; U.S. Pat. Nos. 7,538,189; 7,534,814; 7,531,685; 7,528,131; 7,521,421; 7,514,068; 7,511,013; and US Patent Application Publication Nos. 20090137457; 20090131485; 20090131363; 20090118238; 20090111840; 20090105338; 20090105307; 20090105147; 20090093422; 20090088416; and 20090082471, the methods are hereby incorporated by reference.

The isotope-labeled compounds of the invention can be used as standards to determine the effectiveness of TRPV1 ligands in binding assays. Isotope containing compounds have been used in pharmaceutical research to investigate the in vivo metabolic fate of the compounds by evaluation of the mechanism of action and metabolic pathway of the nonisotope-labeled parent compound (Blake et al. J. Pharm. Sci. 64, 3, 367-391 (1975)). Such metabolic studies are important in the design of safe, effective therapeutic drugs, either because the in vivo active compound administered to the patient or because the metabolites produced from the parent compound prove to be toxic or carcinogenic (Foster et al., Advances in Drug Research Vol. 14, pp. 2-36, Academic press, London, 1985; Kato et al., J. Labeled Comp. Radiopharmaceut., 36(10):927-932 (1995); Kushner et al., Can. J. Physiol. Pharmacol., 77, 79-88 (1999).

In addition, non-radio active isotope containing drugs, such as deuterated drugs called “heavy drugs,” can be used for the treatment of diseases and conditions related to TRPV1 activity. Increasing the amount of an isotope present in a compound above its natural abundance is called enrichment. Examples of the amount of enrichment include from about 0.5, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 12, 16, 21, 25, 29, 33, 37, 42, 46, 50, 54, 58, 63, 67, 71, 75, 79, 84, 88, 92, 96, to about 100 mol %. Replacement of up to about 15% of normal atom with a heavy isotope has been effected and maintained for a period of days to weeks in mammals, including rodents and dogs, with minimal observed adverse effects (Czajka D. M. and Finkel A. J, Ann. N.Y. Acad. Sci. 1960 84: 770; Thomson J. F., Ann. New York Acad. Sci. 1960 84: 736; Czakja D. M. et al., Am. J. Physiol. 1961 201: 357). Acute replacement of as high as 15%-23% in human fluids with deuterium was found not to cause toxicity (Blagojevic N. et al. in “Dosimetry & Treatment Planning for Neutron Capture Therapy”, Zamenhof R, Solares G and Harling 0 Eds. 1994. Advanced Medical Publishing, Madison Wis. pp. 125-134; Diabetes Metab. 23: 251 (1997)).

Stable isotope labeling of a drug can alter its physico-chemical properties such as pKa and lipid solubility. These effects and alterations can affect the pharmacodynamic response of the drug molecule if the isotopic substitution affects a region involved in a ligand-receptor interaction. While some of the physical properties of a stable isotope-labeled molecule are different from those of the unlabeled one, the chemical and biological properties are the same, with one exception: because of the increased mass of the heavy isotope, any bond involving the heavy isotope and another atom can be stronger than the same bond between the light isotope and that atom. Accordingly, the incorporation of an isotope at a site of metabolism or enzymatic transformation can slow said reactions, potentially altering the pharmacokinetic profile or efficacy relative to the non-isotopic compound.

Ureas of general formula (I-a) can be prepared as described in Scheme 1. Amines of formula (I) are commercially available or known in the art (WO2005/016915, WO2010/0016285) and can be reacted first with N,N′-disuccinimidyl carbonate (DSC) in the presence of a base such as but not limited to pyridine, and in a solvent such as acetonitrile, to provide intermediate (2) that is subsequently with amine nucleophiles of formula (3) in the presence of an amine base such as but not limited to diisopropylethylamine, to provide ureas of general formula (4).

The requisite amines of general formula (3) are commercially available or known in the art (WO2010045401; WO2010045402; Voight, E. A., et al., Tetrahedron Letters, 2010, 51 (45), 5904-5907; US 20080287676; Gomtsyan, A., et al., J. Med. Che., 51, 392-395) or can be prepared by any of several methods and synthetic intermediates selected by one of ordinary skill in the art as described in the schemes described herein below. As shown in Scheme 2, hydroxy benzoic acids of general formula (4) can be reacted with excess methyllithium in a solvent such as diethyl ether at reduced temperatures (less than about 20° C.) to provide methyl ketones of general formula (5). Methyl ketones (5) can be reacted with ketones of general formula (6) to provide chromanones of general formula (7). Non-limiting examples of ketones (6) include acetone and 3-pentanone. The reaction is generally performed in the presence of an amine base such as pyrrolidine, in a protic solvent such as but not limited to methanol. Ketones of general formula (7) can be treated with a variety of chiral hydride sources known to those skilled in the art (Corey, E. J. et al. J. Org. Chem. 1988, 53, 2861; Kawanami, S. et al. Tetrahedron 2003, 59, 8411; Corey, E. J. et al. Tetrahedron Asymm. 2002, 13, 1347) to provide chiral alcohols of general formula (8). Alcohols (8) can be converted to azides of general formula (9) by activation with a sulfonylating agent such as but not limited to methanesulfonic anhydride, followed by displacement with a nucleophile azide source such as but not limited tetrabutylammonium azide (Burgard, A. et al. Tetrahedron 1999, 55, 7555). It is to be noted that the transformation of (8) to (9) proceeds with net overall inversion of absolute stereochemistry. Finally, amines of general formula (10) can be obtained by reduction of azides (9) by treatment with a phosphine agent such as triphenylphosphine (PPh₃) under aqueous conditions with an appropriate water-miscible organic co-solvent such as but not limited to THF (Gololobov, Y. G. et al. Tetrahedron 1981, 37, 437). Alternatively, amines of general formula (10) can be obtained by reduction of azides (9) by treatment with hydrogen gas in the presence of a catalyst such as but not limited to Raney nickel (Ra—Ni) in a solvent such as but not limited to methanol. Chiral amines of formula (10) can be converted to compounds of formula (11) using synthetic methods as outlined in Scheme 1.

Racemic amines of general formula (3) wherein L is a bond can be prepared from the corresponding ketones (12) as shown in Scheme 3. Ketones (12) can be treated with hydroxyamines or alkoxyamines such as methoxyamine to provide oximes of general formula (13). The oxime group of (13) can be reduced using methodologies known by one skilled in the art, for example, by hydrogenolysis in the presence of a catalyst such as palladium on carbon to provide the amines of general formula (14).

As shown in Scheme 4, amines of general formula (16) can be prepared according to the general procedure described by Ellman and co-workers (Tanuwidjaja, J.; Ellman, J. A. et al. J. Org. Chem. 2007, 72, 626). Ketones of general formula (12) can be condensed with a chiral sulfinamide such as tert-butanesulfinamide in the presence of a Lewis acid such as Ti(OEt)₄ to provide N-sulfinyl imine intermediates that can undergo a subsequent in situ reduction with reagents such as sodium borohydride to provide sulfinamides of general formula (15). Treatment of sulfinamides of general formula (15) with acetyl chloride and methanol in a solvent such as but not limited to methyl tert-butyl ether provides amine hydrochloride salts of general formula (16).

The requisite ketones of general formula (12) wherein A is CH, X¹ is O, p is 0, and n is 2 can also be prepared by any of several methods and synthetic intermediates selected by one of ordinary skill in the art as described in Schemes 5-6. As shown in Scheme 5, phenols of general formula (17) can be treated with a propargyl bromide and a base such as but not limited to potassium carbonate in a nonpolar solvent such as but not limited to toluene to provide aryl ethers of general formula (18). Reaction of (18) with NCS in the presence of silver acetate in a solvent such as but not limited to acetone affords chloro alkyne derivatives of general formula (19). Upon heating of chloro alkynes of general formula (19) in a solvent such as but not limited to ethylene glycol, cyclization occurs to give chromanones of general formula (12a).

In a related approach shown in Scheme 6, phenols of general formula (17) can be treated with 3-chloropropanoyl chloride in the presence of strong acid activators such as but not limited to TFA and triflic acid to afford directly chromanones of general formula (12a).

Certain amine intermediates can be further functionalized using the sequence described in Scheme 7. Fluorinated amines of general formula (20) wherein m′ is 1 or 2 can be protected as the corresponding tert-butoxy carbamates of general formula (21) using tert-butoxycarbonyl anhydride and an amine base such as but not limited to triethylamine Reaction of (21) with a strong base or combination of strong bases such as but not limited to, n-butyllithium, potassium tert-butoxide, and/or sec-butyllithium, in a solvent such as but not limited to THF effects deprotonation adjacent to the fluorine. It can be appreciated by those skilled in the art that these organometallic intermediates can be reacted with a wide variety of electrophilic reagents (R⁴¹X) wherein R⁴¹ is alkyl or haloalkyl and X is Cl, Br, or I. Non limiting examples of R⁴¹X include hexachloroethane and methyl iodide. Subsequent removal of the Boc protecting group with a strong acid, such as but not limited to, TFA provides amines of general formula (22).

The requisite substituted methyl ketones (6) shown in Scheme 2 can be prepared by the methods described in Schemes 8 and 9. For example, phenols of general formula (17) can be protected and subsequently subjected to direct ortho-metalation as shown in Scheme 9. Treatment of (17) with methoxymethyl chloride in the presence of a non-nucleophilic amine base such as diisopropylethylamine in an aprotic solvent such as dichloromethane provides protected phenols of general formula (23). Other examples of suitable phenol oxygen protecting groups are known in the art. Reaction of (23) with an organolithium base such as n-butyllithium in a solvent at reduced temperature (such as THF at −78° C.) followed by quenching with carbon dioxide and subsequent exposure to mineral acid provides hydroxy benzoic acids of general formula (24). Hydroxy benzoic acids (24) can be transformed to methyl ketones (6) using the chemistry described in Scheme 2.

Substituted methyl ketones (6) also can be prepared according to Scheme 9. Phenols of general formula (17) can be treated with an acetylating agent, such as but not limited to, acetyl chloride in the presence of a base, such as but not limited to, pyridine to generate esters of general formula (25). Subjection to a Lewis acid such as but not limited to aluminum trichloride in a solvent such as but not limited to dichloroethane provides methyl ketones of general formula (6).

The regiochemistry of attachment of the amino or methylamino substituent on the chroman ring can be varied as described in Schemes 10-11.

E. BIOLOGICAL DATA

(i) Capsaicin Activation Assay

Dulbecco's modified Eagle medium (DMEM) (with 4.5 mg/mL glucose) and fetal bovine serum were obtained from Hyclone Laboratories, Inc. (Logan, Utah). Dulbecco's phosphate-buffered saline (D-PBS) (with 1 mg/mL glucose and 3.6 mg/l Na pyruvate, without phenol red), L-glutamine, hygromycin B, and Lipofectamine® were obtained from Life Technologies (Grand Island, N.Y.). G418 sulfate was obtained from Calbiochem-Novabiochem Corp. (San Diego, Calif.). Capsaicin (8-methyl-N-vanillyl-6-nonenamide) was obtained from Sigma-Aldrich, Co. (St. Louis, Mo.). Fluo-4 AM (N-[4-[6-[(acetyloxy)-methoxy]-2,7-difluoro-3-oxo-3H-xanthen-9-yl]-2-[2-[2-[bis[2-[(acetyloxy)methoxy]-2-oxyethyl]amino]-5-methylphenoxy]ethoxy]phenyl]-N-[2-[(acetyloxy)methoxy]-2-oxyethyl]-glycine, (acetyloxy)methyl ester) was purchased from Molecular Probes (Eugene, Oreg.).

The cDNA for human TRPV1 (hTRPV1) was isolated by reverse transcriptase-polymerase chain reaction (RT-PCR) from human small intestine poly A+ RNA supplied by Clontech (Palo Alto, Calif.) using primers designed surrounding the initiation and termination codons identical to the published sequences (Hayes et al. Pain 2000, 88, 205-215). The resulting cDNA PCR products were subcloned into pCIneo mammalian expression vector (Promega) and fully sequenced using fluorescent dye-terminator reagents (Prism, PerkinElmer Applied Biosystems Division) and a PerkinElmer Applied Biosystems Model 373 DNA sequencer or Model 310 genetic analyzer. Expression plasmids encoding the hTRPV1 cDNA were transfected into HEK293 cells using Lipofectamine®. Forty-eight hours after transfection, the neomycin-resistant cells were selected with growth medium containing 800 μg/mL Geneticin (Life Technologies, formerly Gibco BRL). Surviving individual colonies were isolated and screened for TRPV1 activity. Cells expressing recombinant TRPV1 were maintained at 37° C. in DMEM containing 4 mM L-glutamine, 300 μg/mL G418 (Calbiochem) and 10% fetal bovine serum under a humidified 5% CO₂ atmosphere.

The functional activity of compounds at the TRPV1 receptor was determined by measurement of intracellular Ca²⁺ levels ([Ca^(2+]) _(i)) using the Fluorescence Imaging Plate Reader (FLIPR)TETRA®. All compounds were tested over a 12-point one-third-log concentration range. Compound stocks, 10 mM, were prepared in DMSO, and diluted serially across a 384-well plate using a Bravo BenchCel workstation (Agilent Technologies, Santa Clara, Calif.). A stock concentration of capsaicin (10 mM) was made in DMSO, and diluted in D-PBS to a final concentration of 200 nM (4×). On the day prior to the experiment, the recombinant HEK293 cells expressing human TRPV1 (hTRPV1) were removed from tissue culture flasks and plated in growth medium into black-walled clear-bottom 384-well Biocoat™ poly-D-lysine assay plates (BD Biosciences, Bedford, Mass.) using a Multidrop® dispenser (ThermoScientific, Waltham, Mass.). On the day of the experiment, growth medium was removed, and the no-wash FLIPR® Calcium-4 dye (λ_(EX)=470-495 nm, λ_(EM)=515-575 nm; Molecular Devices, Sunnyvale, Calif.) was added to each well using the Multidrop® dispenser. The plated cells were incubated for 90-120 minutes in the dark at room temperature and then test compound was added to each well. Three minutes later, 200 nM capsaicin (4×) solution was added to each well in an amount sufficient to provide a final assay volume of 80 μL and capsaicin concentration of 50 nM. Fluorescence readings were made at 1 to 5 second intervals over the course of the experimental run. The peak increase in relative fluorescence units (minus baseline) was calculated, and expressed as a percentage of the 50 nM capsaicin (control) response. Curve-fits of the data were solved using a four-parameter logistic Hill equation in GraphPad Prism® (GraphPad Software, Inc., San Diego, Calif.), and IC₅₀ values (concentration of the test compounds that inhibits 50% of the intracellular Ca²⁺ concentration increase induced by capsaicin) were calculated.

Selected compounds also were tested in 1321N1 cells expressing recombinant human TRPV1 as a confirmation of potency in a cell line of neuronal lineage. The cDNA for human TRPV1 (hTRPV1) was isolated and the resulting cDNA PCR products were subcloned into pCIneo mammalian expression vector (Promega) as discussed above. Expression plasmids encoding the hTRPV1 cDNA were transfected into 1321N1 human astrocytoma cells using Lipofectamine®. Forty-eight hours after transfection, the neomycin-resistant cells were selected with growth medium containing 800 μg/mL Geneticin (Life Technologies, formerly Gibco BRL). Surviving individual colonies were isolated and screened for TRPV1 activity. Cells expressing recombinant TRPV1 were maintained at 37°C. in DMEM containing 4 mM L-glutamine, 300 μg/mL G418 (Calbiochem) and 10% fetal bovine serum under a humidified 5% CO₂ atmosphere.

Table 1 reports the IC₅₀ values calculated for the compounds tested in the recombinant HEK293 cell assay. Many of the compounds exhibited an IC₅₀ (cap) value less than about 1000 nM, for example, in the range of about 500 nM to about 1000 nM, or in the range of about 100 to about 500 nM, or in the range of about less than 100 nM. As illustrated by the data in Table 1, the claimed compounds are TRPV1 antagonists that inhibit an increase in cellular calcium in response to capsaicin (50 nM) addition.

(ii) Acid Activation Assay

Dulbecco's modified Eagle's medium (DMEM) with 4.5 m g/mL D-glucose, fetal bovine serum, L-glutamine, and 2-morpholinoethanesulfonic acid (MES) were purchased from Sigma-Aldrich Co. (St. Louis, Mo.). Dulbecco's phosphate-buffered saline (DPBS) with Ca²⁺, Mg²⁺, and 1 mg/mL D-glucose (pH 7.4), Geneticin®, 0.25% trypsin-1 mM EDTA, and penicillin-streptomycin were purchased from Invitrogen Corp. (Carlsbad, Calif.). The FLIPR® Calcium 4 assay kit was purchased from Molecular Devices (Sunnyvale, Calif.).

The cDNA for human TRPV1 (hTRPV1) was isolated by reverse transcriptase-polymerase chain reaction (RT-PCR) from human small intestine poly A+ RNA supplied by Clontech (Palo Alto, Calif.) using primers designed surrounding the initiation and termination codons identical to the published sequences (Hayes et al. Pain 2000, 88, 205-215). The resulting cDNA PCR products were subcloned into pCIneo mammalian expression vector (Promega) and fully sequenced using fluorescent dye-terminator reagents (Prism, PerkinElmer Applied Biosystems Division) and a PerkinElmer Applied Biosystems Model 373 DNA sequencer or Model 310 genetic analyzer. Expression plasmids encoding the hTRPV1 cDNA were transfected into HEK293 cells using Lipofectamine®. Forty-eight hours after transfection, the neomycin-resistant cells were selected with growth medium containing 800 μg/mL Geneticin (Life Technologies, formerly Gibco BRL). Surviving individual colonies were isolated and screened for TRPV1 activity. Cells expressing recombinant TRPV1 were maintained at 37° C. in DMEM containing 4 mM L-glutamine, 300 μg/mL G418 (Calbiochem) and 10% fetal bovine serum under a humidified 5% CO₂ atmosphere.

The functional activity of compounds at the TRPV1 receptor was determined by measurement of intracellular Ca²⁺ levels ([Ca²⁺]_(i)) using the Fluorescence Imaging Plate Reader (FLIPR)TETRA®. All compounds were tested over a 12-point one-half-log concentration range with 37.5 μM being the maximum concentration tested. Compound stocks, 10 mM, were prepared in DMSO, and diluted serially across a 384-well plate using a Bravo BenchCel workstation (Agilent Technologies, Santa Clara, Calif.). On the day prior to the experiment, the recombinant HEK293 cells expressing human TRPV1 (hTRPV1) were removed from tissue culture flasks and plated in growth medium into black-walled clear-bottom 384-well Biocoat™ poly-D-lysine assay plates (BD Biosciences, Bedford, Mass.) using a Multidrop® dispenser (ThermoScientific, Waltham, Mass.). On the day of the experiment growth medium was removed, and the no-wash FLIPR® Calcium-4 dye (λ_(EX)=470-495 nm, λ_(EM)=515-575 nm) was added to each well using the Multidrop® dispenser. The plated cells were incubated for 90-120 min in the dark at 25° C. The test compounds dissolved in DMSO were then added to the plates using an Agilent Bravo workstation (Agilent Technologies Inc., Santa Clara, Calif.). Three minutes later, a pH 5.0 solution was added to each well. Reagents were delivered at a rate of 40 μL/sec, and the final assay volume was 80 μL. Acidic pH solutions were prepared by titration of DPBS/MES with 1 N HCl. The intensity of the fluorescence was captured and digitally transferred to an interfaced PC. The maximum peak measured for the concentration range tested was used to calculate the corresponding peak increase in fluorescence over baseline (relative fluorescence units) which was expressed as the percentage (max % remain) of the maximal pH 5.0-induced response.

Table 1 reports the percentage (max % remain) of the maximal pH 5.0-induced response measured for the compounds tested in the recombinant HEK293 cell assay. Most of the compounds tested inhibited calcium flux only partially following TRPV1 activation by the pH 5.0 solution. For example, the maximum % remaining for many of the compounds tested was at least 25% (i.e., the compounds blocked the pH 5.0 induced activation of TRPV1 by no more than 75%).

(iii) Rat Tail Immersion Protocol:

Compounds were tested for their effects on noxious thermosensation using the tail immersion assay. Testing was performed one hour following oral administration of 100 μmol/kg of the compound in 10% ethanol/20% Tween-80/70% PEG-400 (2 mL/kg). Mophine (6 mg/kg) was administered interperitoneally (i.p.) using saline (2 mL/kg) as the vehicle. For testing, a circulating water bath was heated to 55° C. Thirty to sixty minutes post dosing, the rats were handled for a few seconds to calm them down and then cupped with their back against the testers hand at a slight angle with head facing away from tester. With rat in one hand and a 0.01 second stopwatch in the other hand, the tail was quickly immersed 6-8 cm in water bath or to a distance leaving 2-3 cm of tail out of water. The timer was started simultaneously. When the rat flinched or attempted withdrawal, timer was immediately stopped and the rat's tail was quickly removed from water bath. This response latency (in seconds) was recorded. Process was repeated 3 times with 3-4 minutes between readings for a final average.

For a given compound, a percent increase in the average response latency (in seconds) for tail withdrawal relative to a vehicle control was determined % increase=[(t _(c) −t _(v))/t _(v)]×100%

t_(c)=response time (in seconds) with oral dosing of compounds

t_(v)=response time (in seconds) with oral dosing of vehicle

The % increases in tail withdrawal latency relative to vehicle control were divided into the following categories:

+++ is greater than or equal to 25% increase

++ is greater than or equal to 10% but less than 25% increase

+ is less than 10% increase

− is no statistically significant increase relative to vehicle control

Table 1 reports the % increase in tail withdrawal latency measured for the compounds tested. Specifically, Examples 1-39, Examples A-E (shown below), and morphine were tested in the rat tail immersion assay at one hour post dosing (100 μmol/kg). Many of the compounds tested imparted little or no impairment of the subject's ability to sense noxious temperature. For example, many of the compounds tested showed less than a 10% increase in tail withdrawal latency in rats when administered orally, relative to those that were dosed with vehicle.

There are numerous recognized animal models for studying pain. Generally, these pain models mimic one of the mechanisms of pain (e.g. nociceptive, inflammatory, or neuropathic), rather than the pain associated with any one disease or injury. Such models provide evidence of whether a drug or therapy would be effective in treating any of a number of injuries, diseases, or conditions that generate pain via a particular mechanism. Exemplary animal models of pain include, but are not limited to, the rat acute capsaicin-induced flinching behavior and sodium iodoacetate-induced knee joint osteoarthritic pain model discussed below.

Rat Acute Capsaicin-Induced Flinching Behavior:

Rats were placed in individual observation cages. Following an acclimation period of 30 minutes, selected compounds were administered orally at a dose of 100 nmol/kg in a vehicle (10% ethanol/20% Tween 80/70% polyethylene glycol-400) at a volume of 2 mL/kg. One hour after administration of the compound, 2.5 μg of capsaicin in a 10 μL solution of 10% ethanol/90% hydroxypropyl-β-cyclodextrin was injected subcutaneously into the dorsal aspect of the right hind paw. The observation cage was then suspended above mirrors in order to facilitate observation. Rats were observed for a continuous period of five minutes. The number of flinching behaviors of the injured paw was recorded during the five minute observation period (Gilchrist, H. D.; Allard, B. L.; Simone, D. A.; Enhanced withdrawal responses to heat and mechanical stimuli following intraplantar injection of capsaicin in rats. Pain, 1996, 67, 179-188). The percent reduction in the number of flinching behaviors produced from oral administration of the test compounds relative to control-treated animals (% effect) is reported in Table 2.

(iv) Sodium Iodoacetate-Induced Knee Joint Osteoarthritic Pain Model

Unilateral knee joint osteoarthritis was induced in the rats by a single intra-articular (i.a.) injection of sodium iodoacetate (3 mg in 0.05 mL sterile isotonic saline) into the right knee joint cavity under light isoflurane anesthesia using a 26 G needle. The dose of the sodium iodoacetate (3 mg/i.a.injection) was selected based on results obtained from preliminary studies wherein an optimal pain behavior was observed at this dose. Pain behavioral assessment of hind limb grip force was conducted by recording the maximum compressive force exerted on the hind limb strain gauge setup, in a commercially available grip force measurement system (Columbus Instruments, Columbus, Ohio). The grip force data was converted to a maximum hindlimb cumulative compressive force (CFmax) (gram force)/kg body weight for each animal. The analgesic effects of test compounds were determined 20 days following the i.a. injection of sodium iodoacetate. The vehicle control group for each compound being tested was assigned 0% whereas the age matched naïve group was assigned as being 100% (normal). The % effect for each dose group was then expressed as % return to normalcy compared to the naïve group. Test compounds were administered orally in 10% ethanol/20% Tween 80/70% polyethylene glycol-400 vehicle at a volume of 2 mL/kg. The assessment of the analgesic effects of test compounds was made 1 hour following oral administration. The assessment of the analgesic effects of test compounds can be made following a single dose or following repeated administration wherein the frequency of dosing is 1 to 2 times daily. The duration of such repeated daily dosing may last for any time greater than one day. A typical duration of repeated daily dosing is about 5 days to about 12 days. Table 3 illustrates that representative compounds tested showed a statistically significant change in hind limb grip force strength versus a vehicle-dosed control after administration of a single acute oral dose.

(v) Drug-Induced Thermosensory Impairment in Human Subjects (Water Bath Test)

Compounds can be tested for drug-induced thermosensory impairment in human subjects using a temperature-controlled water bath. Specifically, a temperature-controlled water bath is maintained at a constant temperature of 49° C. The subject immerses his or her hand (dominant hand preferred) in the water bath up to the distal wrist crease with the palm side down and withdraws the hand from the water upon first experiencing discomfort. The time taken by the subject to withdraw his or her hand from the water bath is recorded. The water bath test is performed once on the day prior to initial dosing of test compound and again on the morning of initial dosing but prior to administration of the test compound. Test compound is administered daily and the water bath test is performed at a time that corresponds to maximal exposure of the test compound.

The data in Tables 1, 2, and 3 demonstrate that the present compounds are TRPV1 antagonists and are expected to have promising effect of treating or preventing the various diseases and conditions described herein.

The present compounds can be used to treat pain as reported in Nolano, M. et al., Pain, 1999, 81, 135-145; Caterina, M. J. and Julius, D., Annu. Rev. Neurosci., 2001, 24, 487-517; Caterina, M. J. et al., Science, 2000, 288, 306-313; Caterina, M. J. et al., Nature, 1997, 389, 816-824.

Physiological pain is an important protective mechanism designed to warn of danger from potentially injurious stimuli from the external environment. The system operates through a specific set of primary sensory neurons and is activated by noxious stimuli via peripheral transducing mechanisms (see Millan in Prog. Neurobiol., 1999, 57, 1-164 for a review). These sensory fibers are known as nociceptors and are characteristically small-diameter axons with slow conduction velocities. Nociceptors encode the intensity, duration and quality of noxious stimulus and by virtue of their topographically organized projection to the spinal cord, the location of the stimulus. The nociceptors are found on nociceptive nerve fibers of which there are two main types, A-delta fibers (myelinated) and C fibers (non-myelinated). The activity generated by nociceptor input is transferred, after complex processing in the dorsal horn, either directly, or via brain stem relay nuclei, to the ventrobasal thalamus and then on to the cortex, where the sensation of pain is generated.

Pain can generally be classified as acute or chronic. Acute pain begins suddenly and is short-lived (usually twelve weeks or less). It is usually associated with a specific cause such as a specific injury and is often sharp and severe. It is the kind of pain that can occur after specific injuries resulting from surgery, dental work, a strain or a sprain. Acute pain does not generally result in any persistent psychological response. In contrast, chronic pain is long-term pain, typically persisting for more than three months and leading to significant psychological and emotional problems. Common examples of chronic pain are neuropathic pain (e.g. painful diabetic neuropathy, postherpetic neuralgia), carpal tunnel syndrome, back pain, headache, cancer pain, arthritic pain and chronic post-surgical pain.

When a substantial injury occurs to body tissue, via disease or trauma, the characteristics of nociceptor activation are altered and there is sensitization in the periphery, locally around the injury and centrally where the nociceptors terminate. These effects lead to a heightened sensation of pain. In acute pain, these mechanisms can be useful in promoting protective behaviors that can better enable repair processes to take place. The normal expectation would be that sensitivity returns to normal once the injury has healed. However, in many chronic pain states, the hypersensitivity far outlasts the healing process and is often due to nervous system injury. This injury often leads to abnormalities in sensory nerve fibers associated with maladaptation and aberrant activity (Woolf & Salter, Science, 2000, 288, 1765-1768).

Clinical pain is present when discomfort and abnormal sensitivity feature among the patient's symptoms. Patients tend to be quite heterogeneous and can present with various pain symptoms. Such symptoms include: 1) spontaneous pain which can be dull, burning, or stabbing; 2) exaggerated pain responses to noxious stimuli (hyperalgesia); and 3) pain produced by normally innocuous stimuli (allodynia: Meyer et al. Textbook of Pain, 13-44 (1994)). Although patients suffering from various forms of acute and chronic pain can have similar symptoms, the underlying mechanisms can be different and can, therefore, require different treatment strategies. Pain can also therefore be divided into a number of different subtypes according to differing pathophysiology, including nociceptive, inflammatory and neuropathic pain.

Nociceptive pain is induced by tissue injury or by intense stimuli with the potential to cause injury.

Pain afferents are activated by transduction of stimuli by nociceptors at the site of injury and activate neurons in the spinal cord at the level of their termination. This is then relayed up the spinal tracts to the brain where pain is perceived (Meyer et al., Textbook of Pain, 13-44 (1994). The activation of nociceptors activates two types of afferent nerve fibers. Myelinated A-delta fibers transmit rapidly and are responsible for sharp and stabbing pain sensations, whilst unmyelinated C fibers transmit at a slower rate and convey a dull or aching pain. Moderate to severe acute nociceptive pain is a prominent feature of pain from central nervous system trauma, strains/sprains, burns, myocardial infarction and acute pancreatitis, post-operative pain (pain following any type of surgical procedure), post-traumatic pain, renal colic, cancer pain and back pain. Cancer pain can be chronic pain such as tumor related pain (e.g. bone pain, headache, facial pain or visceral pain) or pain associated with cancer therapy (e.g. post-chemotherapy syndrome, chronic postsurgical pain syndrome or post radiation syndrome). Cancer pain can also occur in response to chemotherapy, immunotherapy, hormonal therapy or radiotherapy. Back pain can be due to herniated or ruptured intervertebral discs or abnormalities of the lumber facet joints, sacroiliac joints, paraspinal muscles or the posterior longitudinal ligament. Back pain can resolve naturally but in some patients, where it lasts over 12 weeks, it becomes a chronic condition, which can be particularly debilitating.

Neuropathic pain is currently defined as pain initiated or caused by a primary lesion or dysfunction in the nervous system. Nerve damage can be caused by trauma and disease and thus the term neuropathic pain' encompasses many disorders with diverse etiologies. These include, but are not limited to, peripheral neuropathy, diabetic neuropathy, post herpetic neuralgia, trigeminal neuralgia, back pain, cancer neuropathy, HIV neuropathy, phantom limb pain, carpal tunnel syndrome, central post-stroke pain and pain associated with chronic alcoholism, hypothyroidism, uremia, multiple sclerosis, spinal cord injury, Parkinson's disease, epilepsy and vitamin deficiency. Neuropathic pain is pathological, as it has no protective role. It is often present well after the original cause has dissipated, commonly lasting for years, significantly decreasing a patient's quality of life (Woolf and Mannion Lancet 1999, 353, 1959-1964). The symptoms of neuropathic pain are difficult to treat, as they are often heterogeneous even between patients with the same disease (Woolf and Decosterd Pain Supp. 1999, 6, S141-S147; Woolf and Mannion Lancet 1999, 353, 1959-1964). They include spontaneous pain, which can be continuous, and paroxysmal or abnormal evoked pain, such as hyperalgesia (increased sensitivity to a noxious stimulus) and allodynia (sensitivity to a normally innocuous stimulus).

The inflammatory process is a complex series of biochemical and cellular events, activated in response to tissue injury or the presence of foreign substances, which results in swelling and pain (Levine and Taiwo, Textbook of Pain, 45-56 (1994)). Arthritic pain is the most common inflammatory pain.

Rheumatoid disease is one of the commonest chronic inflammatory conditions in developed countries and rheumatoid arthritis is a common cause of disability. The exact etiology of rheumatoid arthritis is unknown, but current hypotheses suggest that both genetic and microbiological factors can be important (Grennan & Jayson, Textbook of Pain, 397-407 (1994)). It has been estimated that almost 16 million Americans have symptomatic osteoarthritis (OA) or degenerative joint disease, most of whom are over 60 years of age, and this is expected to increase to 40 million as the age of the population increases, making this a public health problem of enormous magnitude (Houge & Mersfelder Ann. Pharmacother. 2002, 36, 679-686; McCarthy et al., Textbook of Pain, 387-395 (1994)). Most patients with osteoarthritis seek medical attention because of the associated pain. Arthritis has a significant impact on psychosocial and physical function and is known to be the leading cause of disability in later life. Ankylosing spondylitis is also a rheumatic disease that causes arthritis of the spine and sacroiliac joints. It varies from intermittent episodes of back pain that occur throughout life to a severe chronic disease that attacks the spine, peripheral joints and other body organs. Fernihough, J. et al. describe in Neurosci. Lett. 2005, 75-80 a potential role for TRPV1 in the manifestation of pain behavior accompanied by osteoarthritis changes in the knee.

Compounds described herein are TRPV1 antagonists and thus are useful in ameliorating acute and chronic inflammatory pain and postoperative pain as demonstrated in Honore, P. et al., J. Pharmacol. Exp. Ther. 2005, 410-421.

Another type of inflammatory pain is visceral pain, which includes pain associated with inflammatory bowel disease (IBD). Visceral pain is pain associated with the viscera, which encompass the organs of the abdominal cavity. These organs include the sex organs, spleen and part of the digestive system. Pain associated with the viscera can be divided into digestive visceral pain and non-digestive visceral pain.

Commonly encountered gastrointestinal (GI) disorders that cause pain include functional bowel disorder (FBD) and inflammatory bowel disease (IBD). These GI disorders include a wide range of disease states that are currently only moderately controlled, including, with respect to FBD, gastro-esophageal reflux, dyspepsia, irritable bowel syndrome (IBS) and functional abdominal pain syndrome (FAPS), and, in respect of IBD, Crohn's disease, ileitis and ulcerative colitis, all of which regularly produce visceral pain. Elevated TRPV1 immunoreactivity has been observed in colonic sensory nerve fibers in patients with IBD (Szallasi, A. et al., Nature Rev., 2007, 6, 357-373).

Other types of visceral pain include the pain associated with dysmenorrheal, cystitis and pancreatitis and pelvic pain.

It should be noted that some types of pain have multiple etiologies and thus can be classified in more than one area, e.g. back pain and cancer pain have both nociceptive and neuropathic components.

Other types of pain include: pain resulting from muscular-skeletal disorders, including myalgia, fibromyalgia, spondylitis, sero-negative (non-rheumatoid) arthropathies, non-articular rheumatism, dystrophinopathy, glycogenolysis, polymyositis and pyomyositis; heart and vascular pain, including pain caused by angina, myocardial infarction, mitral stenosis, pericarditis, Raynaud's phenomenon, scleredoma and skeletal muscle ischemia; head pain, such as migraine (including migraine with aura and migraine without aura), cluster headache, tension-type headache mixed headache and headache associated with vascular disorders; and orofacial pain, including dental pain, optic pain, burning mouth syndrome and temporomandibular myofascial pain. It has been shown that CGRP-receptor antagonists block the vasodilatation effects of CGRP and exhibits efficacy in patients with migraine and cluster headaches. CGRP is strongly co-expressed in many TRPV1 expressing nerve fibers, it is plausible that activation of TRPV1 could partially underlie a neurogenic-mediated component of headache.

Another type of pain is ocular pain (eye pain), which includes pain associated with dry eye syndrome, increased intraocular pressure, glaucoma, accidental trauma, and surgical procedures. intraocular pressure. Activation of TRPV1 induces inflammatory cytokine release in corneal epithelium in the eye (Zhang, F. et al., J. Cell. Physiol., 2007, 213, 730; Murata, Y. et al., Brain Res., 2006, 1085, 87). Retinal ganglion cell apoptosis induced by elevated hydrostatic pressure arises substantially through TRPV1, likely through the influx of extracellular Ca²⁺ (Sappington, R. M. et al., Invest. Ophth. Vis. Sci., 2009, 50, 717). TRPV1 antagonists can effectively reduce symptoms of dry eye without causing anesthesia effects on the ocular surface (US2009/0131449). Silencing of TRPV1 by administration of siRNA can be a useful therapy in the treatment of ocular pain associated with dry eye syndrome and could reduce side effects associated with medications currently used to treat patients suffering from this pathology. Investigators at Sylentis have reported data indicating that an siRNA targeting TRPV1 could be used to decrease the behavioral response of guinea pigs to ocular surface irritation (Association for Research in Vision and Ophthalmology Meeting, 2008). Administration of the TRPV1 agonist capsaicin resulted in a significant increase in irritation parameters compared with saline and that topical administration of TRPV1 siRNA twice a day for three days resulted in reduced scratching and wiping movements for up to nine days in the treated eyes. The reported analgesic effect was greater than that observed using the reference standard capsazepine.

It is known that capsaicin, a TRPV1 agonist, induces cough and reduced airway conductance in human clinical trials. TRPV1 antagonists such as capsazepine have been shown to block capsaicin and citric acid-induced cough responses in guinea pigs as demonstrated by Geppetti P. et al., Eur. J. Pharmacol., 2006, 533, 207-214. Thus, TRPV1 antagonists demonstrate potential in the treatment of asthma, cough, chronic obstructive pulmonary disease (COPD) and bronchoconstriction as demonstrated by Watanabe N. et al., Pulmonary Pharmacol. Ther., 2005, 18, 187-197; and Jia Y. et al., Br. J. Pharmacol., 2002, 137, 831-836.

Present compounds can be used to treat bladder overactivity and/or urinary incontinence as demonstrated by Fowler, C., Urology, 2005, 65, 400-405.

Present compounds can be used to treat inflammatory thermal hyperalgesia as demonstrated by Davis, J. et al., Nature, 2000, 405, 183-187.

Present compounds can be used for the treatment of anxiety-related disorders as demonstrated by Marsch, R. et al., J. Neurosci., 2007, 27, 832-839.

Present compounds can be used for the treatment of disorders associated with hyperdopaminergia such as psychosis, attention deficit hyperactivity disorder and schizophrenia as demonstrated by Tzavara, E. et al., Biol. Psych., 2006, 59, 508-515.

Present compounds can be used for the treatment of diabetes and obesity as demonstrated by Suni, A. and Sallazi, A., Trends Pharmacol. Sci., 2008, 29, 29-36.

Ischemia (e.g. cerebral ischemia) is the shortage or inadequate of oxygenated blood flow to body parts and organs, and often results in dysfunction or damage of tissue. The neuroprotective efficacy of induced hypothermia following or during cerebral ischemia is evident in experimental anima models of stroke (Barone, F. C. et al., Neurosci. Biobehav. Rev., 1997; 2(1), 31-44; Onesti, S. T. et al., Neurosurgery, 1991, 29, 369; Coimbra, C. et al., Acta Neuropathol. (Berl), 1994; 87, 325; Zhang, Y. et al., Acta Anaesthesiol. Sin., 2001, 39, 65; Yamashita, K. et al., Stroke, 1991, 22, 1574; Ooboshi, H. et al., Brain Res., 2000, 884, 23; Colbourne, F. et al., J. Cereb. Blood Flow Metab., 2000, 20(1-2), 1702; Kawai, N. et al., Stroke, 2000, 3, 1982; Maier, C. M. et al., J. Neurosurg., 2001, 94, 90; Maier, C. M. et al., Stroke, 1998, 29, 2171). Two trials conducted in cardiac arrest patients have demonstrated improved neurological outcome of inducing hypothermia (Mild therapeutic hypothermia to improve the neurologic outcome after cardiac arrest: Bernard, S. A. et al., N. Engl. J. Med., 2002, 346, 549; and N. Engl. J. Med., 2002, 346, 557). Induction of hypothermia by lowering of the core temperature has been attempted by mechanical devices such as surface cooling using catheters placed in a large vessel. However, such mechanical devices have been shown to have considerable side effects, including shivering, serious infections, and lung puncture. Regulation of the core body temperature by pharmaceutical compositions comprising TRPV1 agonists as a safer and less expensive alternative to the mechanical method was discussed in WO2008/040360 and WO2008/040361. Such treatments can have unintended side effects such as the sensation of burning pain, known to be elicited by TRPV1 agonists. TRPV1 antagonists that are capable of inducing hypothermia can be used for the treatment of ischemia without the pungent effects.

Present compounds can be administered alone, or in combination with one or more other compounds described herein, or in combination (i.e. co-administered) with one or more additional pharmaceutical agents. For example, a compound of the present invention, or a pharmaceutically acceptable salt, prodrug, or solvate thereof, can be administered in combination with an analgesic (e.g. acetaminophen, or an opioid such as morphine), or with a nonsteroidal anti-inflammatory drug (NSAID) such as, but not limited to, aspirin, diclofenac, diflusinal, etodolac, fenbufen, fenoprofen, flufenisal, flurbiprofen, ibuprofen, indomethacin, ketoprofen, ketorolac, meclofenamic acid, mefenamic acid, meloxicam, nabumetone, naproxen, nimesulide, nitroflurbiprofen, olsalazine, oxaprozin, phenylbutazone, piroxicam, sulfasalazine, sulindac, tolmetin and zomepirac; or administered with a combination of an analgesic (e.g. acetaminophen, opioids) and an NSAID. In certain embodiments, the nonsteroidal anti-inflammatory drug (NSAID) is ibuprofen. In certain embodiments, the analgesic is acetaminophen. Combination therapy includes administration of a single pharmaceutical dosage formulation containing one or more of the compounds described herein and one or more additional pharmaceutical agents, as well as administration of the compounds of the invention and each additional pharmaceutical agent, in its own separate pharmaceutical dosage formulation. For example, a compound of formula (I) and one or more additional pharmaceutical agent(s) can be administered to the patient together, in a single oral dosage composition having a fixed ratio of each active ingredient, such as a tablet or capsule; or each agent can be administered in separate oral dosage formulations.

Where separate dosage formulations are used, the present compounds and one or more additional pharmaceutical agents can be administered at essentially the same time (e.g., concurrently) or at separately staggered times (e.g., sequentially).

Actual dosage levels of active ingredients in the pharmaceutical compositions can be varied so as to obtain an amount of the active compound that is effective to achieve the desired therapeutic response for a particular patient, compositions and mode of administration. The selected dosage level can depend upon the activity of the particular compound, the route of administration, the severity of the condition being treated and the condition and prior medical history of the patient being treated. However, it is within the skill of the art to start doses of the compound at levels lower than required to achieve the desired therapeutic effect and to gradually increase the dosage until the desired effect is achieved.

When used in the above or other treatments, a therapeutically effective amount of one of the compounds can be employed in pure form or, where such forms exist, in pharmaceutically acceptable salts thereof. The present compounds can also be administered as a pharmaceutical composition comprising the compound of interest in combination with a pharmaceutically acceptable carrier. The phrase “therapeutically effective amount” of the compound of the invention means a sufficient amount of the compound to treat disorders, at a reasonable benefit/risk ratio applicable to any medical treatment. It can be understood, however, that the total daily usage of the compounds and compositions can be decided by the attending physician within the scope of sound medical judgment. The specific therapeutically effective dose level for any particular patient can depend upon a variety of factors including the disorder being treated and the severity of the disorder; activity of the specific compound employed; the specific composition employed; the age, body weight, general health, sex and diet of the patient; the time of administration, route of administration, and rate of excretion of the specific compound employed; the duration of the treatment; drugs used in combination or coincidental with the specific compound employed; and like factors well-known in the medical arts. For example, it is well within the skill of the art to start doses of the compound at levels lower than required to achieve the desired therapeutic effect and to gradually increase the dosage until the desired effect is achieved.

The total daily dose of the compounds administered to a human or lower animal range from about 0.10 μg/kg body weight to about 25 mg/kg body weight. More preferable doses can be in the range of from about 0.10 μg/kg body weight to about 1 mg/kg body weight. If desired, the effective daily dose can be divided into multiple doses for purposes of administration. Consequently, single dose compositions can contain such amounts or submultiples thereof to make up the daily dose.

F. PHARMACEUTICAL COMPOSITIONS

Described herein are also pharmaceutical compositions comprising of a compound described herein, or a pharmaceutically acceptable salt, prodrug, or solvate thereof, formulated together with a pharmaceutically acceptable carrier. The pharmaceutical compositions can be formulated for oral administration in solid or liquid form, for parenteral injection or for rectal administration.

The compounds identified by the methods described herein can be administered as the sole pharmaceutical agent or in combination with one or more other pharmaceutical agents. For example, the compounds or salts or solvate thereof can be combined with an analgesic, or with a nonsteroidal anti-inflammatory drug (NSAID, or with a combination of an analgesic and an NSAID. Thus, the present invention also includes pharmaceutical compositions which are comprised of therapeutically effective amount of a compound identified by the methods described herein, or pharmaceutically acceptable salt, prodrug, or solvate thereof, a pharmaceutical agent as disclosed hereinabove, and a pharmaceutically acceptable carrier.

The term “pharmaceutically acceptable carrier” as used herein, means a non-toxic, inert solid, semi-solid or liquid filler, diluent, encapsulating material or formulation auxiliary of any type. Some examples of materials which can serve as pharmaceutically acceptable carriers are sugars such as lactose, glucose and sucrose; starches such as corn starch and potato starch; cellulose and its derivatives such as sodium carboxymethyl cellulose, ethyl cellulose and cellulose acetate; powdered tragacanth; malt; gelatin; talc; cocoa butter and suppository waxes; oils such as peanut oil, cottonseed oil, safflower oil, sesame oil, olive oil, corn oil and soybean oil; glycols; such a propylene glycol; esters such as ethyl oleate and ethyl laurate; agar; buffering agents such as magnesium hydroxide and aluminum hydroxide; alginic acid; pyrogen-free water; isotonic saline; Ringer's solution; ethyl alcohol, and phosphate buffer solutions, as well as other non-toxic compatible lubricants such as sodium lauryl sulfate and magnesium stearate, as well as coloring agents, releasing agents, coating agents, sweetening, flavoring and perfuming agents, preservatives and antioxidants can also be present in the composition, according to the judgment of one skilled in the art of formulations.

The pharmaceutical compositions can be administered to humans and other mammals orally, rectally, parenterally, intracisternally, intravaginally, intraperitoneally, topically (as by powders, ointments or drops), bucally or as an oral or nasal spray. The term “parenterally,” as used herein, refers to modes of administration, including intravenous, intramuscular, intraperitoneal, intrasternal, subcutaneous, intraarticular injection and infusion.

Pharmaceutical compositions for parenteral injection comprise pharmaceutically acceptable sterile aqueous or nonaqueous solutions, dispersions, suspensions or emulsions and sterile powders for reconstitution into sterile injectable solutions or dispersions. Examples of suitable aqueous and nonaqueous carriers, diluents, solvents or vehicles include water, ethanol, polyols (propylene glycol, polyethylene glycol, glycerol, and the like, and suitable mixtures thereof), vegetable oils (such as olive oil) and injectable organic esters such as ethyl oleate, or suitable mixtures thereof. Suitable fluidity of the composition can be maintained, for example, by the use of a coating such as lecithin, by the maintenance of the required particle size in the case of dispersions, and by the use of surfactants.

These compositions can also contain adjuvants such as preservative agents, wetting agents, emulsifying agents, and dispersing agents. Prevention of the action of microorganisms can be ensured by various antibacterial and antifungal agents, for example, parabens, chlorobutanol, phenol, sorbic acid, and the like. It also can be desirable to include isotonic agents, for example, sugars, sodium chloride and the like. Prolonged absorption of the injectable pharmaceutical form can be brought about by the use of agents delaying absorption, for example, aluminum monostearate and gelatin.

In some cases, in order to prolong the effect of a drug, it is often desirable to slow the absorption of the drug from subcutaneous or intramuscular injection. This can be accomplished by the use of a liquid suspension of crystalline or amorphous material with poor water solubility. The rate of absorption of the drug can depend upon its rate of dissolution, which, in turn, can depend upon crystal size and crystalline form. Alternatively, a parenterally administered drug form can be administered by dissolving or suspending the drug in an oil vehicle.

Suspensions, in addition to the active compounds, can contain suspending agents, for example, ethoxylated isostearyl alcohols, polyoxyethylene sorbitol and sorbitan esters, microcrystalline cellulose, aluminum metahydroxide, bentonite, agar-agar, tragacanth, and mixtures thereof

If desired, and for more effective distribution, the compounds can be incorporated into slow-release or targeted-delivery systems such as polymer matrices, liposomes, and microspheres. They can be sterilized, for example, by filtration through a bacteria-retaining filter or by incorporation of sterilizing agents in the form of sterile solid compositions, which can be dissolved in sterile water or some other sterile injectable medium immediately before use.

Injectable depot forms are made by forming microencapsulated matrices of the drug in biodegradable polymers such as polylactide-polyglycolide. Depending upon the ratio of drug to polymer and the nature of the particular polymer employed, the rate of drug release can be controlled. Examples of other biodegradable polymers include poly(orthoesters) and poly(anhydrides) Depot injectable formulations also are prepared by entrapping the drug in liposomes or microemulsions which are compatible with body tissues.

The injectable formulations can be sterilized, for example, by filtration through a bacterial-retaining filter or by incorporating sterilizing agents in the form of sterile solid compositions which can be dissolved or dispersed in sterile water or other sterile injectable medium just prior to use.

Injectable preparations, for example, sterile injectable aqueous or oleaginous suspensions can be formulated according to the known art using suitable dispersing or wetting agents and suspending agents. The sterile injectable preparation also can be a sterile injectable solution, suspension or emulsion in a nontoxic, parenterally acceptable diluent or solvent such as a solution in 1,3-butanediol. Among the acceptable vehicles and solvents that can be employed are water, Ringer's solution, U.S.P. and isotonic sodium chloride solution. In addition, sterile, fixed oils are conventionally employed as a solvent or suspending medium. For this purpose any bland fixed oil can be employed including synthetic mono- or diglycerides. In addition, fatty acids such as oleic acid are used in the preparation of injectables.
